Sometimes, it’s easier to create an alias when working with the Unix command line. Having to create these every time seems to defeat the point of having a short alias though. Luckily, you can make them persistent.

Lets assume that we are using a user called mike. We need to be in our home directory.

If you’re running CentOS, you may find yourself frustrated that you have GCC 4.2 or older, when you need to be running at least 4.3 for some features – for example, if you want to compile HipHop for PHP.

Never fear, you don’t need to compile a compiler from source!

As well as the gcc RPMs in the repository, there are also a set for GCC 4.4, appropriately enough named gcc44 and you can install them in the usual way.

Following on from my previous post about installing ImageMagick from source, to get it working with Apache you need to do the following. First, we need to install something from Pecl. So make sure you have the pecl command at hand – if not, install it.

There is an RPM available for ImageMagick on Debian, but it isn’t the most update to date, so if you need all the new features, you’ll need to compile and install it from source. Luckily, it’s very easy to do.
